Q fever in dairy cattle has been investigated in Latvia since 2012. In 2015, 10.7% of farms tested positive for the DNA of C. burnetii, its aetiological agent, in bulk tank milk. The presence of C. burnetii DNA and infectious bacteria in dairy products has been assessed in several countries, and because Latvian milk may contain them, parallel assessment in this country is recommended. Accordingly, the present study tested shop and farm retail dairy products from Latvia and included foreign products for comparison.

Spore-forming bacteria are a group of bacteria can form spore and they grow aerobically and anaerobically as Bacilli and Clostridia spp. This group of bacteria has public health hazards and economic loss significance. This study was designed to determine the prevalence of spore-forming bacteria isolated from marketable milk and some dairy products as pasteurized milk, UHT milk, milk powder, and baby food (30 samples of each). The samples were purchased randomly from different dairy shops, supermarkets, and pharmacies in Assiut Governorate, Egypt. Bacillus cereus was detected in 23.33, 13.33, 6.66, 13.33, and 10% from marketable milk, pasteurized milk, UHT milk, milk powder, and baby food, respectively. While, Clostridium perfringens was recovered in 20, 6.66, 0, 3.33 and 0%, respectively. This study concluded that there is a need for hygienic measures must be applied in the milk and dairy products production and manufacture to minimize the possibility of entering the spore-forming bacteria in these products.

Objective: The goal of this study was to determine the levels of lead (Pb), cadmium (Cd), and aluminum (Al) in raw bovine milk. Milk consumption was used to calculate the estimated weekly intake (EWI), provisional tolerable weekly intake (PTWI), and target hazard quotient (THQ) for individuals. Metal distribution in dairy products and byproducts was studied as a result of artisanal processing. Material and Methods: Seventy-five raw bovine milk samples were collected from artisanal producers in Alexandria city, West Delta, Egypt, and analyzed using the atomic absorption spectrophotometer. The effect of artisanal dairy processing on metal distribution was studied. Results: The averages of Pb, Cd, and Al in milk samples were 45.06, 4.77, and 2.93 μg/l, with 13.33% and 1.33% of analyzed samples had Pb and Al levels higher than the permissible limits, respectively. The EWI values of Pb, Cd, and Al were 1.050, 0.111, and 0.068 μg/kg body weight, which contributed to about 4.20%, 1.59%, and 0.97% from the PTWI, respectively. The THQ of three metals was [J Adv Vet Anim Res 2021; 8(3.000): 454-464]
